Item Acesso aberto (Open Access) Microwave switchable frequency selective surface with high quality factor resonance and low polarization sensitivity(2012-12) KAWAKATSU, Marcelo Nobuyuki; DMITRIEV, Victor AlexandrovichWe present a microwave switchable frequency selective surface with high quality factor transmission resonance. The high quality resonance is achieved by excitation of the trapped-mode in array with two concentric metal rings in a cell on a silicon substrate. Optical activation of the silicon substrate permits to switch off the transmission band.
